SPECIFICATION forming part of Letters Patent No. 319,797, dated June E), 1885.

7 Application filed March 5 1885. (No model.)

T0 at whom, it may concern/.-

Be it known that I, HENRY W. DEAN, of Boston, county of Suffolk, and State of Massachusetts, have invented an Improvement in Lasting-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object toimprove the construction of lasting-machines.

In my improved machine the last containing the boot or shoe to be lasted is mounted at its heel upon a heel rest or pin, and at its toe upon a toe-rest, and the heel and toe clamping plates are then closed by hand upon and so as to embrace the upper at theheel and toe of thelast. The main shaft is then started, and the heel and toe crimping jaws are moved bodily forward partly over the heel and the toe ofthe last. Thetoeofthelastislifted. The side rubbers are then elevated to bring their upper edges up to the edge of the bottom of the last, thus straining the upper about the top of the last. The side jaws are moved forward over the last, laying the edges of the upper thereon over on the inner sole on the last, and thereafter the heel and toe jaws are closed to complete the crimping of the upper at the heel and toe, and at the same time the heel of the last is elevated. In order to shorten the stroke and better control the movement of the heel and toe crimping jaws, I have mounted the pivot of the jaws on a slide-plate, and have placed the usual roller or other studs at the rear ends of the jaws into diagonal slots made in a jaw-closing slide-plate, rather than in a stationary plate, as heretofore, and I have provided independent means for moving both the said plates in the proper order of time. The spring of the bottom of the last varies very considerably in different shops, and every style of shoe has its peculiar spring, and one of the most difficult things in lasting has been to readily adapt the side lasting-jaws to the spring of the last and to lasts of different lengths or sizes. To obviate this difficulty, I have devised novel side lasting devices, composed of long fingers pivoted at their rear ends to permit them to be readily turned more or less, and between their ends the said finmore or less oscillate the adjacent guide, and

consequently tip the finger held therein or thereon out of true horizontal line from edge to edge, thus causing each of the said fingers to accommodate its under fiat side to the spring of the last. These guides are independently adjustable, to thereby enable each finger to be placed in any desired vertical position,according to the spring of the last. For longer or shorter lasts a greater or less number of fingers may be employed, the number employed being determined by the length of the last. The guides and the end bearings for the side lasting devices or fingers are mounted upon horizontally-movable carriages.

The particular features in which my-invention consists will be pointed out in the claims at the end of this specification.

The frame-work A, of suitable shape to sustain the working parts, has suitable boxes to sustain the main rotating or cam shaft A, it having splincd upon it the cams A A -one to actuate the heel and the other the toe crimpin g devices, to be described-each cam having like cam-grooves 2 3, the shape of which is best shown in Fig. 15, the said grooves being, however, made as rights and lefts. The camshaft A has fast on it the cams A A The frame-work A, at its top and along its sides, is provided with suitable guideways for the reception of the like carriages B B, which are engaged at their under sides (see Fig. 4) by the upper ends of levers B B, pivoted at B, and provided at their lower ends with roller or other-studs, 13*, that enter the diagonal slots B in the cross-head B it having a suitable roller or other stud, which enters a camgroove, 5, (see Fig. 6,) in the cam A the reciprocation of the said erosshead causing, the said carriages to be reciprocated toward and from the center line of the last. Each earriage has suitable cross-pieces thereon, which receive the screws 6, having fast collars 7 thereon just below their heads, .the space between the head of each screw and its collar 7 being used to receive the slotted foot of the end bearing, a, the latter near its upper end having an opening for the reception of the tang 8 at the rear end of the side lasting-finger, G, the said tang being retained therein loosely'by a suitable bolt or catch, a, actuated by a spring, 10, (see'Fig. 12,) and pref erably shielded by a shield, a, therear end of each finger 0 so held being free to oscillate in the said end hearing, as may be desired. Each finger O is extended through a guide or box, 1), (shown in detail, Fig. 14,) and each guide has, at each side, a slotted ear, b. These ears b are extended into guide adjusting and holding devices I), (see Fig. 16,) made as loops held between the under side of the head of a screw, 12, and a collar, 13, thereon, the said screws entering and being made adjustable in a cross-beam of the carriage B. Byv turning the screw 12 the guide adjusting and holding device b may be raised or lowered, and, acting each one upon one of the ears bof the guides 12, the latter guides are tipped more or less, thereby turning the fingers C more or less out of true horizontal position in the direction of their width, causing the said fingers to occupy different positions one with relation to the other, thereby adapting each finger to the spring or curve of the last immediate] y at thatpoint where the said finger is to'pass over the edge of the last to lay the upper at the sides and shank thereof, over upon the bottom of the. last or the inner sole thereon, to be then fastened in the usual way.

The toe-rest is composed of a block, d, (see Fig. 4,) pivoted upon a post, d, supported by a spring, 14, (see Fig. 3,) the said shank being placed in a suitable guide, herein shown as a box, (1 held loosely by the screws 15 in slots 16 therein, thesaid guide at its lower end having a roller, 17, which is acted upon by the cam A when the toe'rest is to be lifted, as described, which is done immediately after the toe-crimping jaws are moved forward, the said cam A being fast to the cam-cylinder A. The heel support or pin a is pivoted upon a small block, 0, held loosely in a shank, c guided atits lower end in a guide, a, the said shank being provided with an elongated central opening, 18, to receive the main shaft A. The shank c has a laterally-projecting roller-stud, 19, that enters a cam-groove, 20, (see Figs. 3 and 4,) in one face of the cam A the said cam-groove being of such shape as to lift the heel support or pin and the heel of the last after the heel-crimping jaws have been moved forward and while they are being closed, such lifting of the heel-pin to thus break down and better set the leather and counter at the heel end of the shoe. At its end the frame-work has suitable guideways for the reception of the heel and toe carriages E F, provided with depending legs that receive between them, re-

spectively, the cam hubs or cylinders A A", projections from each end of the said hubs entering the said legs, one of the said projections having fast on it the cam A. The top plates of the carriage E F, both alike, have suitable guideways to receive one of the slide-plates 6, having pivoted upon them at e the crimping-jaws 0, each jaw having a roller or other stud, 22, (see Fig. 10,) that enters a ICC slot, 28, in a jaw-closing slide-plate, f, (see Figs. 1 and 11,) also fitted to slide longitudinally in guideways of the said carriage. The slide-plate e has a lug, 23, that is engaged by the upper end of a lever, 24, of the first order,-the said lever at its lower end having a roller or other stud or pin that engages a slide-block, 25, (see Fig. 9,) held between suitable guide-ledges, 27, of the said carriage, the block 25 having a roller or other stud, 26, that enters the camgroove 2 of one of the camhubs A or A. Thelever 24 moves the slideplate 6 only longitudinally. The jaw-closing slide-platef is connected, asherein shown, by a bail or link, 29, with the'upper end of a lever, 30, of the first order, it at its lower end engaging a slide-block, 31, held and guided by the ledges 27, the said slide-block having a roller or other stud, 32, to enter one of the cam grooves 3 of oneof the cam-hubs A or A". The cam-grooves 2 and 3 are parallel for part of their length, and while the-studs 26 and 32 are in the parallel parts of the said grooves the slideplate e is moved forward, and at such time it will be understood that the crimpingjaws e carried by the said plates are not closed; but at the proper time during the further r0- tation of the said cam-hubs A A the camgroove 3, acting on the stud 32, moves the block 31, lever 30, and plate f forward, causing the cam-slots 28, by their action on the stud 22, to close the crimping-jaws at the toe and heel of the shoe, the said jaws during their closing movement, as described, about their pivots e not necessarily being moved forward. The heel and toe crimping jaws are both alike, so the same letters have been used to designate like parts, and the description of one of them will suffice for both. The heel and to carriages, provided, respectively, with threaded nuts E F, receive in the said nuts a shaft, G, provided with right and left threads, the rotation of the said shaft enabling the toe and heel carriages to be adjusted toward and from each other, according to the length of the boot or shoe to be lasted. The toe and heel carriages each have a spring-plate, g, of usual shape, to come in contact with the upper at the toe and heel of thelast. The side rubbers are composed ofleversH H, pivoted at 33 on a vertically-movable cross head, H, the upper ends of the said levers having connected to them by the screws 34 the shanks h of spring-arms H, the upper ends of which, curved to conform substantially to the outlines of the inner and outer sides of the last, are faced with indiarubber or leather, as at h, the said material being connected with the said spring-arms by suitable pins, 35. These side rubbers having the spring arms, as described, are free to adapt themselves to the thickness of the last and the upper thereon, and are caused to act upon and are moved vertically while in contact with the upper, to thus stretch the upper about the last preparatory to moving the side lasting-fingers, C, over the last. The crosshead H is provided with a roller or other stud, 36, which enters a cam-groove, 37, in the cam A*, fast on the shaft A. The lower ends of the levcrsH are acted upon by springs H, that normally act to cause the rubbers to hug the last or the boot or shoe thereon, and the said levers H are also connected by a cord or chain, m, joinedwith a foot or other lever, m, the free end of which enters a suitable guide having teeth or notches, (see Fig. 2,) as usual, by which to hold the said lever in place.

WVhen the last is to be put on the heel pin or support, or is to be removed therefrom, the operator will depress the treadle m.

Fig. 2 clearly shows the fingers adjusted i nto position to accommodate them to the spring of the last.

The guides b and the'guide adjusting and holding devices I) constitute a flexible or jointed support for the side lasting devices or fingers, G, at a point back from their working ends, the said guides and adjusting devices resembling a chain, and, if desired, the guides scribed, but one screw in number more than the number of fingers used need be employed to adjust all the fingers; but if the said guides were not loosely connected each with the other, at least two screws would'be needed to adjust each guide, and the use of these extra screws would not permit the close arrangement of the fingers.

I do not broadly claim adjustable side lasting-fingers.

I claim- 1. In a lasting-machine, the series ofguides b and the guide adjusting and holding devices b loosely connecting the guides together, and the bearings a, and the horizontally-arranged fingers O, placed in the said guides, combined with screws to adjust the guides vertically and hold them in place, and with a side lasting-carriage to move the said fingers and their supports, to operate as described.
